I use Maple 15 and I want to take the real and the imaginary part of a simple expression e.g. 5*Dirac(x)+3*I, having already assumed x a real value. However, Maple seems to have problem with the Dirac function. The output looks like this:

I have two inequalities in the complex variable z, called "ineq" and "ineq2". When I issue the following plotting command, I can show the region of the complex plane that satisfies both inequalities: It appears as a black region:

Maple gives me the complete solution to the attached PDE. This solution is expressed in terms of KummerU and KummerM. What I want is to obtain the solution for real numbers only, i.e. I want to get rid of the possible imaginary numbers in the solution. This implies that the separation constant, _c1, must be less or equal to 2r.

How can I do this?

Furthermore, the four arbitrary constants will need to be determined through boundary conditions....

Im trying to calculate scientific error propagation with data from Excel. Unfortunately Im having troubles making the package work. What I want to do is import a list from Excel with values, and another list of the error of each value.

The problem comes when using the Combine function on the imported arrays from excel.Could anyone help me work this out? I feel it should be possible for Maple to import tables from Excel, calculate the propagated error. ...
